Seeds from the brightly coloured sunflower pack a nutritional punch. This energy-dense snack was prized by Native American tribes. Spanish explorers brought sunflower seeds back to the Old World with them from the sunflower's native America, according to the National Sunflower Association. Sunflower seed hulls have no nutritional value and cannot be digested. Many people dehull sunflower seeds by cracking the shell between their teeth and spitting it out, but this will not work if you need the seeds for baking, or in large quantities. Dehull your sunflower seeds properly to access a large quantity of the crunchy kernels inside.
Add a handful of the sunflower seeds to the work bowl of a food processor.
Cover the processor and pulse several times until you see the hulls separate from the kernels.
Pour the entire contents of the food processor into a bowl of water where the kernels sink to the bottom and the broken hulls float.
Skim the hulls from the surface of the water with a slotted spoon or skimmer.
Pour the rest of the bowl of water through a colander to drain the dehulled sunflower seed kernels. Use your kernels in cooking or as a snack.
